BOB-SLED.

` Specification of Letters Patent.

Patented May 26, 1908.

Application filed June 12, 1907. Serial No. 378,559.

To all/whom it may concern:

Be 1t known that I, LESLIE D. JANNELL,

of Rumford Falls, in the county of Oxford and State of Maine, haveinvented certain new and useful Improvements in Bob-Sleds, of which thefollowing is a specification.

This invention relates to sleds such as are used in logging operationsfor hauling logs, the chief parts of the sled being a pair of runnersand a cross beam, usually termed a bunk, supported by the runners, andextending across the space between them, the bunk being elevated abovethe runners so that one end of a log may be placed upon and chained toit, the other end of the log dragging on the track, or resting on thebunk of another sled.

My invention relates particularly to the means for connecting the bunkwith the runners, and it has for its object to provide a strong andserviceable attachment for a sled runner adapted to support one end of abunk in a raised position above the runner, and to provide a looseconnection between the bunk and runner which will permit a certainfreedom of independent movement' of the runner relatively to the bunk,such as is required to prevent injurious or breaking strains when thesled is passing over rough roads.

The invention consists in the improved attachment which I will nowproceed to describe and claim. I Of the accompanying drawings, forming apart of this speciiicatiom-Figure 1 represents a perspective viewshowing the runners and bunk of a bobsled, the runners being providedwith bunk-supporting attachments embodying my invention. Fig. 2represents a side elevation of the same. Fig. 3 represents alongitudinal section of a portion of one of the runners and of theattachment thereon. Fig. 4 represents an end view of the chair whichforms a part of my improved attachment. Fig. 5 represents a section online 5-5 of Fig. 2. Fig. 6 represents a section on line 6.16 of Fig. 2.

vThe same letters of reference indicate the same parts in alltheiigures.

In the drawings 12 12 represent a pair of sled runners, and 13represents a bunk carried by the runners, and extending across the spacebetween them, the bunk being elevated above the runners as usual.

My improved runner attachment for supportingthe bunk, comprises anelongated base 14 adapted to bear on the upper edge of the runner 12,and having downwardly-projecting flanges lvvwhich bear on opposite sidesof the runner, and are secured thereto by bolts 16.

17 17 represent brackets which project up wardly from the base, thebase, its flanges and the brackets being preferably made of cast metalformed in a single piece. The brackets 17 have vertical inner faceswhich are separated from each other by a space adapted to receive achair 18 on which the bunk 13 bears. The chair is provided withupwardly-projecting ears 19, arranged to bear on opposite sides of thebunk, the bottom of the latter resting on the surface of the chairbetween the ears; The chair is provided at opposite sides withoutwardly-projecting lugs 20, which enter sockets 21 formed for theirreception in the opposed inner faces of the brackets 17. The bottom ofthe chair is provided with a downwardly-projecting lug 22, which entersa socket 23 formed for its reception in the intermediate portion of thebase 14, which extends between the brackets 17 The lugs 2O and 22 of thechair fit loosely in the sockets'21 and 23, so that the runner and thebase member, with its brackets, are adapted to oscillate to a limitedextent, both vertically and horizontally, independently of the chair andbunk, provision being thus made for the independent play of the runners,which is necessary in traveling upon rough roads. 24 represents a crossbar, the ends of which are iitted in sockets 25 formed for theirreception in the brackets 17, said cross bar extending across the upperside lof the chair between the ears 19, and preventing the chair frombeing lifted from the base and brackets. The cross bar 24 may bedetachably secured to the brackets by pins 26, or by any other suitablemeans. The chair may be provided with ears 27 at opposite edges of thecross bar, the latter it ting loosely between the ears and assisting thelugs and sockets, above mentioned, in limiting endwise movement of thechair rela tively to the base.

The chair is referably a single piece or casting, comprising arelatively narrow foot 28, which bears on the base 14, a head 29 whichis longer than the foot, and forms a seat for the bunk 13, side webs 30,connecting the foot with the head, and a transverse web 31 extendingbetween the side webs 30. From the opposite edges of the head 29, theears 19 project upwardly. There are preferably two pairs of earsV on thehead, the ears of one pair being higher than those of the other. Thehigher ears project above the permanent bunk 13, and are adapted toengage a supplemental bunk 32, which is used when the sled is used fordragging logs, their rear ends trailing behind the sled. When only onebunk is employed, the ears should both be of the same height. y

Each bracket 17 is preferably com osed of a vertical arm 170, projectingupwar ly from the base, and form-ing one end of the chairreceivingopening, and an inclined brace 171,

which is preferably curved, as shown, the said brace'securely sup ortingthe arm, and by reason of its curved orm, opposing eective resistance toshocks or blows which it may receive from logs, etc. The space betweenthe arm 170 and the brace 171 is preferably occupied by a web 172.

One of the brackets 17 is rovided with an ear or projection 33 ada te toengage a skid or short-log which is p aced on one of the brackets in aninclined position, one end resting on the bracket and being confinedthereon' by the ear 33, while the other end rests on 'the ground at oneside of the sled.` The skid is used to facilitate the loading of logs,one end of the log being rolled upon the skid onto the bunk.4

It will be observed that the lugs 20 project base adapted to bear on arunner and having upwardly-projectingarrns forming sides of achair-receiving opening, said arms and theA intermediate portion of thebase being provided with sockets, and a chair composed of a foot bearingon the intermediate portion of the base, a head forming a bunk seat,side webs connecting the head with the foot, a transverse web connectingthe side webs, and bunk-engaging ears projecting upwardly from the head,the foot and the side webs of the Vchair being provided with lugs whichloosely engage said sockets.

In testimony whereof I have affixed my signature, in presence of twowitnesses.
